Summary

This is figure 5A from US Patent 5,539,310 by Peter J. Basser, James H. Mattiello, and Denis Le Bihan, granted July 23, 1996. Images appearing in a US Patent are public domain unless a specific copyright exclusion is posted, and no such exclusion appears in this patent:

“Patents are published as part of the terms of granting the patent to the inventor. Subject to limited exceptions reflected in 37 CFR 1.71(d) & (e) and 1.84(s), the text and drawings of a patent are typically not subject to copyright restrictions.” See: http://www.uspto.gov/main/ccpubguide.htm

37 CFR 1.84(s) Copyright or Mask Work Notice (§ 1.71(d). “A copyright or mask work notice may appear in the drawing, but must be placed within the sight of the drawing immediately below the figure representing the copyright or mask work material and be limited to letters having a print size of.32 cm. to .64 cm. (1/8 to 1/4 inches) high. The content of the notice must be limited to only those elements provided for by law. For example, ‘‘ 1983 John Doe” (17 U.S.C. 401) and ‘‘*M* John Doe” (17 U.S.C. 909) would be properly limited and, under current statutes, legally sufficient notices of copyright and mask work, respectively. Inclusion of a copyright or mask work notice will be permitted only if the authorization language set forth in 1.71(e) is included at the beginning (preferably as the first paragraph) of the specification.”

37 CFR 1.71(e) The authorization shall read as follows “A portion of the disclosure of this patent document contains material which is subject to (copyright or mask work) protection. The (copyright or mask work) owner has no objection to the facsimile reproduction by any one of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all (copyright or mask work) rights whatsoever.”
